摘　　要：【目的】研究不同羽系拜城油鸡生长发育规律,为拜城油鸡的科学饲养管理和品种改良提供理论依据。【方法】分别选择0日龄健康的黑麻羽系、黄麻羽系和银灰羽系拜城油鸡雏鸡各200只(公母各半),测定并记录0~22周龄的体重,采用Logistic、Gompertz和Von Bertalanffy生长模型对拜城油鸡公、母鸡的体重进行生长曲线拟合分析。【结果】10、14周龄黑麻羽系公鸡的体重显著高于银灰羽系公鸡的体重(P<0.05),12周龄黑麻羽系公鸡的体重显著高于黄麻羽系和银灰羽系公鸡的体重(P<0.05),16周龄黑麻羽系和黄麻羽系公鸡的体重极显著高于银灰羽系公鸡的体重(P<0.01),20、22周龄黑麻羽系和黄麻羽系公鸡的体重显著高于银灰羽系公鸡的体重(P<0.05);母鸡中,黄麻羽系母鸡的初生重分别显著或极显著高于黑麻羽系和银灰羽系母鸡(P<0.05或P<0.01),6、8周龄黑麻羽系母鸡的体重显著高于银灰羽系母鸡的体重(P<0.05),20、22周龄龄黄麻羽系母鸡的体重显著高于银灰羽系母鸡的体重(P<0.05);3个羽系拜城油鸡的生长曲线均呈现“S”型;3个羽系公鸡均在第10周达到生长高峰,母鸡在第12周达到生长高峰;3种生长模型的拟合曲线与实际曲线基本吻合,Von Bertalanffy模型对公、母鸡的拟合效果最佳(R 2>0.998),黑麻羽系、黄麻羽系和银灰羽系公鸡的拐点周龄分别为8.629、9.389、8.947,拐点体重分别为858.207、911.107、842.681 g;母鸡的拐点周龄分别为7.946、8.619、7.936,拐点体重分别为635.543、679.577、609.097 g。【结论】不同羽系拜城油鸡的生长发育存在差异,3个羽系拜城油鸡公、母鸡的最优生长模型均为Von Bertalanffy模型。【Objective】The experiment aims to understand the growth and development rules of Baicheng County Fried Chicken with different feather,namely black hemp feather,yellow feather,and silvery grey feather,and provide theoretical basis for scientific feeding management and breeding improvement of Baicheng County Fried Chicken.【Methods】200 healthy chicks(half males and half females)of each feather color were selected at the age of 0 days,and their body weight was measured and recorded from 0 to 22 weeks old.Logistic,Gompertz,and Von Bertalanffy growth models were used to fit and analyze the growth curve of male and female Baicheng County Fried Chickens.【Results】At 10 and 14 weeks old,the body weight of male Black hemp feather Baicheng County Fried Chicken was significantly higher than that of male Silvery grey feather Baicheng County Fried Chicken(P<0.05).At 12 weeks old,the body weight of male black hemp feather Baicheng County Fried Chicken was significantly higher than that of male Yellow feather and silvery grey feather Baicheng County Fried Chicken(P<0.05);at 16 weeks old,the body weight of male black hemp feather and yellow feather Baicheng County Fried Chicken was extremely significantly higher than that of male silvery grey feather Baicheng County Fried Chicken(P<0.01),and at 20 and 22 weeks old,the body weight of male black hemp feather and yellow feather Baicheng County Fried Chicken was significantly higher than that of male silvery grey feather Baicheng County Fried Chicken(P<0.05).For female Baicheng County Fried Chicken,the birth weight of yellow feather was significantly or extremely significant higher than that of black hemp feather and silvery grey feather(P<0.05 or P<0.01);at 6 and 8 weeks old,the body weight of female black hemp feather Baicheng County Fried Chicken was significantly higher than that of female silvery grey feather Baicheng County Fried Chicken(P<0.05),and at 20 and 22 weeks old,the body weight of female Yellow feather Baicheng County Fried Chicken was significantly higher
